GetTime Or Wait problem

[Chandra_ni]

Hi..

Time difference between two GetDate/Time calls with a wait function in between shows a lesser time taken than the wait duration specified. How is that possible? Pls see the attached VI. Any thoughts?

Thanks and regards

Chandra

If you use "Highlight Execution", then you will see the behavior you have posted. Otherwise it has no problems.

The get-date time function has a resolution of 16 ms. (or something like that) on Windows ,  the returned timestamp isn't fully accurate. This is an OS limitation.

Ton (if you use the Tick count you will see a wait time of 50/51 ms)

Many thanks for the Tick Count tip.

After your reply, I found this link related to what you mentioned above:

This leads to one more question. Is there any other way we can get the current time with a resolution of 1 ms (in Windows XP)?

Thanks,

Chandra
